How does Microsoft prevent/bill Azure MFA failed authentications in a per-authentication model?

New Contributor

Good day community,

 

A customer considers Azure MFA in a per-authentication model, because they have far more external users than internal employees.

 

Microsoft counts and bills both succesful as failed (denied) authentications, so the customer wonders:

 

What happens if somehow (a hacker/robot) generates tons of failed authentications? Will Microsoft bill the customer accordingly or are there other mechanisms in place to prevent this?

 

Thank you,

Cheers Mike
